'CENTRIFUGAL MACHINE FOR MIXI NG GASES WITH LIQUIDS.

SPEGIFIGATION forming part of Letters Patent No. 542,755, dated July 16, 1895.

Application filed April 13, 1894.

' To all whom it may concern:

Be it known that I, MARTIN EKENBERG, a subject of the King of Sweden and Norway, residing at Stockholm, Sweden, have invented a new and useful Improvementin Centrifugal Machines for Mixing Gases with Liquids, of which the following is a specification.

This invention has forits object to produce a centrifugal machine by means of which gases can be intimately mixed withliquidsas, for instancefin aerating and carbonating water and other liquids.

In the accompanying drawings, Figure 1 is a sectional elevation of my improved centrifugal mixing-machine. Fig. 2 is a horizontal section in line 2 2, Fig.1. Fig. 3 is asectional elevation showing a slightly-modified construction of the machine. Fig. 4 is a vertical section on line 4 4, Fig. 2.

Like letters of referencerefer to like parts 7 in the several figures.

A represents the upper disk and B the lower disk of a centrifugal emulsion-machine. b is the upright spindle to which the lower disk is secured and by which it is rotated. The opposing sides of the two disks are made concave or recessed in the usual way, and the recessed portions of the disks are surrounded by marginal faces 0 and d to hold a sufficient volume of liquid, which are separated'by a narrow interveningspaceorannular slit. The liquid is driven by centrifugal force through this narrow space or slit between the faces of the disks.

The upper disk is preferably made adjustable with reference to thelower disk to regulate the width of the intervening space, and the adjusting devices are preferably those which are represented in Figs. 1 and 2, and which are constructed as follows:

The upper portion 6 of the spindle is enlarged in diameter and provided with a collar f, against the under side of which the lower disk is clamped by a screw-nut g, which is applied to the lower screw-threaded part of the enlarged upper part of the spindle. The

upper disk is provided with a hub h, which rests upon a spring 11, supported on-the collar f, and is pressed down by screw-nutsj, which Serial No. 6071561- (No modeL) .vided with a bore or cavity is, which opens at the upper end of the spindle and extends downwardly to the level of the collar, where it communicates with one or more lateral passages Z, which open through the peripheral face of the collar into the cavity of the lower disk. This bore of the spindle receives the liquid or liquids to be treated from a feedpipe m, and delivers the same through the passages Z into the cavities of the-disks.

N is a stationary casing or gas-chamber which incloses the disks A and B and which is arranged at a suitable distance therefrom. This casing is supplied with the gas which is desired to be cominingled with the liquid. This gas can be conducted to the casing by the pipen or other suitable means. The casing is fitted tightly around the spindle and the liquid-feed pipe, and is so constructed as to retain the gas and to collect the liquid discharged from the rotating disks. This liquid is preferably removed from the casing by a trapped discharge-pipe 0.

19 represents one or more gas-supply passages formed in one or both of the disks A and B in such manner as to extend from the back or outer surface of the disk to the face or inner surface thereof, so that the gas contained in the gas-chamber can pass through this passage into the space between the disks and become there com mingled with the liquid passing outwardly through said space. Each of these gas-passages is preferably provided on the back of the disk with a funnel or mouthpiece p, which opens in the direction in which the disk rotates, and which serves as a gathering device to gather the gas and inject it into the gas-passage, thereby promoting the flow of the gas from the surrounding gas-chamber through said passage into the space between the opposing faces of the disks. The gas which passes through these passages into the space between the disks becomes thoroughly commingled with the liquid in passing through said space, so that the liquid which is discharged from said space at the peripheries of the disks is an intimate mixture of the liquid and gas.

The gas-supply passages may open at their inner ends in the flat marginal faces of the disks, as shownin Fig. 1, or they may open into annular re'cesses or mixing-chambers q, formed in said faces, as shown in Fig. 3.

The gas-supply passages are preferably curved or inclined outwardly, so that their receiving ends are nearer the axis of rotation than their discharge ends, whereby the centrifugal forceis utilized in promoting the flow of the gas through these passages.

While it is desirable in many instances to make provision for adjusting the width of the space between the disks through which the liquid is -discharged and in which it is mixed with the gas, this is not indispensable, and the two disks can be rigidly secured together by bolts 'r and intervening stay-pieces s, as represented in Fig. 3, or by other suitable means. p

The injector funnels or mouthpieces applied to the outer ends of the gas-passages 0f the disks may be omitted, particularly when the gas in the gas-chamber is under pressure, but they are desirable when the gas-pressure is slight or when the gas is not under pressureas, for instance, when the machine is used for aerating-a liquidin which case the surrounding casing need not be gas-tight, but

. charged from the disks.

When the gas which is commingled with the liquid is one which is capable of absorption by the liquid, the effect of the machine is also to bring the liquid in a finely-divided state in contact with the gas and so facilitate the absorption of the gas by the liquid.

It is obvious that two or more liquids can be fed between the disks at the same time for the purpose of commingli'ng the same and at the same time charging the mixture with the gas.

This machine may be used for a variety of purposes, among which may be mentioned thedeodorizing of illsmelling liquid-for instance, liquids containing benzine or carbon disulphid, and the oxidation ofv liquids, for instance, in the manufacture of varnish.

I claim as my invention- 1. A centrifugal machine for mixing a gas with a liquid consisting of a rotating vessel which is provided with a central inlet for the liquid, a cavity surrounding said inlet and receiving the liquid therefrom, a peripheral discharge extending outwardly from said ing from the outer surface of the vessel into theinterior thereof, said gas passages having their inlets arranged nearer the axis of rotation than their outlets, substantially as set forth.

3. A centrifugal machine for mixing a gas with a liquid, consisting of a rotating vessel which is provided with a cavity which receives the liquid, with a peripheral discharge extending outwardly from said cavity, and

with one or more gas supply passages extending from the outer surface of the vessel into the interior'thereof and provided at their receiving ends with gathering devices, substantially as set forth.

4. The combination with a rotating vessel which is provided with a cavity which receives the liquid,'with a peripheral discharge extending outwardly from said cavity and with one or more gas supply passages extending from the outer surface of the vessel into the interior thereof, of a bowl forming a gas supply chamber inclosing said vessel and provided with a gas supply conduit and with a discharge for the liquid, substantially as set forth.
